Our lifetime guarantee covers the tool body and shank. The blades are
covered for 90 days from the date of purchase for breakage under normal
working conditions. Blades will dull faster cutting hardwoods vs
softwoods (peeled or unpeeled). Soil and other abrasive substances will
reduce blade life and is not covered under this warranty. When making a
claim, you must show proof of purchase from an authorized distributor.
This is valid only to the original buyer, and not for tools sold secondhand,
used, or sold “as is” to a second party.
What Voids Warranty
In order to keep our lifetime and 90 day warranty you must AVOID the
following actions:
Operating the tool in a drill press or lathe (or any system other than
a hand-held drill)
Running the tool into a nail or foreign object
Altering or misusing the tool
About Your Product
Thank you for purchasing our Dual Blade - Radius Shoulder Tenon Cutter!
Lumberjack engineers, along with our craftsmen, have designed the
safest, easiest-to-use tenon cutters on the market. By combining old
world skills with 3D CAD modeling and CNC manufacturing, we have
created the ideal tenon cutter: straight tenons, smooth finish, precision
operation, and long life.
Dual-bladed tenon tools will cut a tenon in half the time of a single-bladed
tool. Wear is reduced by putting force of cutting across two blades
instead of one. The blades are stamped, heat treated and precision
ground to provide years of service if properly maintained. The Pro tools
are machined from a solid aluminum billet and the Home tools are made
of die-cast aluminum.

SAFETY
Before beginning any project, carefully read and follow ALL safety and
operational instructions for any tools or devices you will be using. Failure to do
so may cause physical harm to yourself or those around you. If you feel
uncomfortable using our tenon cutters or any other tool, STOP immediately.
Lumberjack Tools assumes no responsibility for injury caused to the operator,
bystander, or tools used in conjunction with the use or misuse of our tenon
cutters.
NEVER OPERATE POWER TOOLS UNDER THE INFLUENCE OF
DRUGS, ALCOHOL, OR ANY MEDICATIONS
ALWAYS WEAR SAFETY GLASSES, DUST MASK, AND ANY OTHER
PERSONAL PROTECTION ITEMS AS NEEDED
NEVER WEAR LOOSE ITEMS THAT COULD BE CAUGHT IN MOVING
PARTS. SECURE LOOSE OR LONG HAIR AWAY FROM AREA
WE STRONGLY RECOMMEND A SINGLE-SPEED, GEAR DRIVEN DRILL
WITH RPMS OF 500 OR LESS. EXCEEDING THESE RPMS MAY
RESULT IN DAMAGE TO THE TOOL
ALWAYS DISCONNECT POWER AND ALLOW DRILL TO COME TO A
COMPLETE STOP BEFORE INSTALLING, REMOVING, OR ADJUSTING
THE TOOL
NEVER APPLY BENDING FORCE (SIDE LOADING) TO THE TOOL. SIDE
LOADING COULD CAUSE THE SHANK TO FAIL, OR MAY RESULT IN
BLADE DAMAGE
ALWAYS SECURE THE LOG IN A VISE OR CLAMP PRIOR TO
STARTING YOUR DRILL. FAILURE TO DO SO MAY RESULT IN INJURY
ALWAYS HANDLE THE BLADES WITH EXTREME CARE! FAILURE TO
DO SO MAY RESULT IN SERIOUS INJURY
WHEN EXCESSIVE FORCE IS REQUIRED TO CUT, RE-SHARPEN OR
REPLACE THE BLADES. A SHARP TOOL IS A SAFE TOOL!
NEVER PUT HANDS OR ANY BODY PART INSIDE THE TOOL WHILE THE
BLADES ARE ATTACHED! DOING SO MAY CAUSE SERIOUS INJURY

Pro Series ONLY
Quick Stop Installation
Install the quick stop pin through
the tool body
Secure with the supplied acorn nut
The length of the tenon is
determined by measuring from
the face of the tool to the bottom
of the Quick Stop Pin and
subtracting 3/4”
In the image to the left, dimension
X” - 3/4” = approximate length of
the tenon

Correct (smaller tenon) Correct (larger tenon) WRONG
The tenon diameter is variable based on the blade offset. Smaller offset
= smaller tenon, larger offset = larger tenon. 3/16” blade offset is a good
place to start, but you will want to test tenon fit in holes to achieve the
correct offset (we recommend writing the results down). DO NOT set the
blades beyond 5/16” or the blade edge will not contact the log and will
not cut.

TIP

Determine tenon length before cutting
The key is to have a gap
between the end of the
tenon and bottom of the
mortise hole
This can be done by making
the tenon 1/8” to 1/4”
shorter than the mortise
hole is deep

Tenon length can be controlled without
having the Industrial Series or Quick

Cut off a piece of tenon to use as a plug
to stop cutting at a set length

information and use the

WARNING: If the log comes loose or unclamped while cutting the
tenon, DO NOT drop the drill or try to grab the log! Stop the drill and
remove it from the end of the log. Re-secure the log, and resume
Obtain the log you want to tenon
Cut it to length and make sure the ends
are flat. If the ends are not even/flat, the
tenon will be crooked
If the log diameter is
larger than the tool can
accept, taper the end
with a draw knife
Secure the log in a vise, clamp,
or fixture with a “V” shaped
notch
The Log Lock (LL1545) is a safe,
easy, economical way to clamp
logs, and is available on our
website

ALWAYS unplug the drill before adjusting the blades or
adjusting the chuck
Make sure the tool is square against the end of the log
before cutting
If the tool is held at an angle the tenon will be cut angled

Carefully install the tenon
cutter into an unplugged 1/2”
drill, and tighten it firmly. Use
the tee handle to tighten the
chuck
Square up to the log so that
the cutter is flush against the
flat face of the log
Apply body pressure by leaning
into the drill
Pull the trigger to cut the tenon
Wait until the drill comes to a
stop before removing the
cutter from the log

Drilling Holes (Mortise)
Additional Tips
It takes time to master using
these tools
Make a plan of what you want
to build before you begin
Have a list of all tools and
materials you will need
Do not over complicate your first
few projects
Practice reading the natural twists
and defects in the wood
Practice cutting tenons and using
the tools on scrap material
Measure and mark the locations of all
holes before drilling
Place the center of the bit on the
desired hole location
Take care to hold the drill perpendicular
to the log
Use a forstner bit (or spade bit) to drill
the hole

Maintenance
Body
- Cleaning
Keep the tenon cutter body clear of sap and other build-up
Always remove the blades before cleaning
Clean the tool with a solvent (such as mineral spirits)
Blades
- Care
Always wipe blades with a thin film of oil at the end of the day
to help prevent oxidation
- Cleaning
Clean the blades with a solvent (such as mineral spirits) and
immediately apply a thin film of oil to prevent oxidation
- Sharpening
Use a sharpening stone or file to re-sharpen the blades, then
clean the blades and apply a thin film of oil
Shank
- Replacement
If your shank breaks, we offer replacement shanks (see first
page for contact information)
Turn the shank counter-clockwise to remove
Turn the shank clockwise to install
WARNING: ALWAYS HANDLE THE BLADES WITH EXTREME CARE!

PROBLEM CAUSE SOLUTION
• Tool Skips off
to one side or
bounces around
• Log is larger than tool will
accept
• Taper down the end of the
log with a draw knife
• Not enough pressure is being
applied • Lean into drill with body
• Not cutting log
• Log is larger than tool will
accept
• Taper down the end of the
log with a draw knife
• Blades are slid too far back • Position blades so they are
back no further than 5/16"
• Blades are dull
• Not applying enough
pressure
• Sharpen blades
• Purchase new blades
• Lean into drill with body
• Takes too
much of a "bite"
• Aggressive cutting from dual
blades
• Remove one blade or
"shim" blade up to .020”
• Crooked Joint • Holding drill crooked while
cutting
• Position the drill square
against the log before cutting
• Drill stops or
cuts on small
diameter logs
but not larger
ones
• Using a variable speed drill
• Make sure you are using a
single-speed drill with low
RPMs
• Using a non-Milwaukee
brand drill
• We recommend purchasing
a Milwaukee brand hole hog
drill
• Spiral grooves
on the tenon
joint
• Lateral wobbling of the drill • Hold the drill as steady as
you can while cutting
• Removing the cutter while
drill is still spinning
• DO NOT remove the cutter
until the drill has come to a
complete stop
